[UE] SetCursorDir

	//onto the internet, however, they do not give me the right vector.

	FRotator newRot = this->GetActorRotation();
	//Using atan2 function to get the degree between our character location and cursor location
	// aka how much we want the character to rotate
	float newYaw = (hitLoc - CurrLoc).Rotation().Yaw;;
	//Using that degree as the Yaw(rotating around Z axis) of our Frotator
	newRot.Yaw = newYaw;

	//in the end, we set it;
